Heavy Duty Suspension Bits

I suspect balljoints and linkages.
My question, where should I be looking for affordable yet extra durable suspension stuff? I've attached a YouTube link to see some of the comical roads I drive on in Nigeria this one to my house.

And possibly this one:

At the time our cars were designed corporate was MBChrysler and there is a fair amount of common/compatible parts between Jeep and Mercedes bigger vehicles.
The R-Class thread goes into Jeep part numbers, even.

I plan to swItch to traditional coils once the bags give up.

I’m more inclined to go to traditional suspension.
What do you folks think about this kit?
Front and Rear Air Spring to Coil Spring Conversion Kit - 4 Piece - Compatible with 2007-2012 Mercedes-Benz GL450 (Excludes ADS and ABS Bracket) https://a.co/d/3feDa7T
Please remember I’m in Africa so choices are limited.
Arnotts warranty means little considering shipping back and forth.
Thanks.
Off the top of my head, I don't think the air springs will fail much quicker due to rough roads. I believe they fail quicker due to environmental effects, such as ultraviolet, ozone, and salt.
If you check the bags' integrity regularly, you should be able to spot a leak before it becomes a bang. And always replace with top quality components, e.g. Bilstein, for longevity.
P.S. I looked at the Amazon selection. A bunch of Chinesium. From the reviews, you can expect them to fall apart in short order, especially if you are driving on Nigerian roads. I would replace your air springs and keep an eye on the coil kits to see if you can find good ones. Be prepared to pay for the pleasure, though.

You might be able to find someone on here who has installed a conversion kit. I seem to remember someone doing so.
I can only offer one observation. To make such a kit, someone has to design the rear springs and have those springs wound. They also have to design a strut body to match the original, and design springs also. They then have to select a damper cartridge to put inside, or even design and and make one themselves. This is all a lot of work, let alone to get right.
If you are Chinese, you will scour the world for products for which the design effort has already been expended, and then copy the results in as low cost a fashion as possible.
You might be able to find a Chinesium version that is good, but there is probably a very small number of manufacturers that took on the copying process because this is a niche product.
I suggest going to U.S. based companies that specialize in custom suspension products. Strutmasters may be such a company; I am not familiar with this market.
Expect that the conversion kit will not be cheap. That does not mean an expensive one is good; a cheap one is a copy, and the odds of the copier getting it right are slim.
Do keep us apprised of your progress. There are plenty of folks on here who would be interested.

and this is the specific post

I am startled by the poster that put ML springs in. Isn't the weight difference between vehicles something like 20%? I would be astonished if his ride height was not significantly different.
I had them installed by an indie shop here for NGN30,000 which is about $40
PS: my right front springs exploded while parked.
Will rise when car starts but goes down again.
I’m temporarily in a wheelchair so can’t do much troubleshooting.
What do you good people think?
I was told that the mechanic that replaced the fronts did not check for leaks.
Thanks.
